Those thrilling days of yesteryear were made so in part thanks to the presence of radio in the homes of Americans seeking information, comfort, or distraction as the U.S. was steered into World War II. The short films "On the Air" (1937), "Radio at War!" (1944), "Voice of Victory" (1944), and "Behind Your Radio Dial" (1948) offer behind-the-scenes looks at concert programs, ham operators, the role of radio in D-Day, and vintage shows like "Fibber McGee and Molly." 83 min. total. Standard; Soundtrack: English.
